Fruit Tree & Insect Control

Semi-dwarf Plum fruit tree in my garden

Tree size:
Miniature tree = 6 - 8' tall
Dwarf tree = 8 to 12 feet tall
Semi-dwarf tree = 12 to 20 feet tall
Semi-dwarf trees are usually stronger and bear fruit faster than dwarf trees.
Most semi-dwarfing rootstocks do not control fruit tree size. Pruning makes a big difference in size. The best way to keep fruit trees smaller is by pruning during summer/fall.

Less toxic “dormant oil" to suffocate overwintering pests, such as aphids and mites. INGREDIENTS
1 cup vegetable oil
2 tablespoon liquid soap
1 gallon water

Insect Control: Horticultural Oils
